Herausforderungen in der

Kommunikationsinfrastruktur

end-to-end IP Kommunikation der IoT Geräte

Erfordert eine Anpassung der Netzwerkfunktionen an die neuen Anforderungen aus dem IoT

BereichManage a large number of devices with variety of IoT protocols

Unterschiedliche implementierte IoT Geräte

MTU differences, simplified vs. full protocol stack (e.g., CoAP/UDP vs. HTTP/TCP)

single stack vs. dual stack

processing and communications bandwidth

sleep schedule, security protocols, etc.

Herausfordernde Interaktion zwischen den Applikationen und der

Infrastruktur

dynamische Kommunikation

Kritische Infrastrukturen

unterschiedliche Zugangstechnologien (z.B.: wireless, wired, 5G, Fiber, …

Offenen Fragen im Zusammenspiel SDN IoT NFV

Wie können neue Kommunikationsstrukturen den Anforderungen

entsprechen?

Wie werden die unterschiedlichen IoT Protokolstacks abgestimme?

Wie kann die Funktionalität der IoT Geräte in der SDN Welt

abgebildet werden?

Wie kann die Network Function Virtualisation NFV von IoT

Funktionen abstrahiert werden?

Wie kann die SDIoT Infrastrukture die erwartete Anzahl von IoT

Geräten verwaltet?

Ist SDN/NFV eine Ermöglicher (enabler) für neue IoT Anwendungen

und Service!

Lesson Learned: A Big Need for Big Tools

What we have• Different requirements on Reliability

What we learned• The Devil is in the Detail

• Things get complex in the brown field

• Each network is different

What we need• Description

• Verification

• Automation

• Monitoring

What we did• The Opossum App for ONOS

• Can do a lot of other Things
